A Simple Salt Swap Could Prevent Millions of Deaths Each Year
Summary
A study modeling salt substitution in 193 countries estimated that potassium-enriched salt could prevent nearly three million deaths and 10 million new cases of cardiovascular and kidney disease each year. The researchers said benefits would be greatest if the substitute replaced salt used both at home and in processed and restaurant foods, but warned that some people with kidney disease or medicines that raise blood potassium need medical advice.Key Facts
